In the half-backs, Luciano Orquera (who needs one more points to reach 100 points scored in all competitions this season) pairs up with scrum-half Tyson Keats.

Up front, Josh Sole is back at number eight to partner Simone Favaro and Nicola Cattina in the back row.

In the second row Aironi can count on Quintin Geldenhuys and captain Marco Bortolami, whilst the front three comprises experienced prop Matias Aguero, hooker Fabio Ongaro and young tighthead prop Lorenzo Romano.

First time

Wales centre Jon Davies will captain the Scarlets for the first time. Dom Day comes back into the second row with Aaron Shingler who returns from a toe injury and, in an unchanged back row, Josh Turnbull is named as vice-captain.

Young Wales and Scarlets Prop Rhodri Jones moves from loosehead prop last weekend to give him an opportunity at tighthead, furthering his development and experience as a key front row player for the future.

"We know this is a must-win game for us out in Italy and the boys have been frustrated after their performance in Brive last weekend in the quarter-final," said Scarlets coach Nigel Davies.

"This is a time or them to get some momentum back and we know we are still in with a fighting chance with our league campaign."
